Definitions

  • the invention relates to a method and device for pre-milling confectionery material, such as chocolate.
  • confectionery material is conventionally pre-milled or pre-refined by a granulometric reduction of the particles forming the mass of said material, this operation being carried out between two rotary cylinders, of which a first cylinder can controllably swing with respect to a second cylinder which is supported at a fixed position.
  • Prior confectionery material making systems comprise pre-refining machines arranged between the mixers and the end refining machines.
  • Said pre-refining machines allow to reduce the particle size of the confectionery material particles to values which would be suitable for the end refining machines. More specifically, said pre-refining machines, due to the reduced granulometry, provide a confectionery material mass having an even doughiness and, accordingly, an even consistency.
  • the variation of the consistency of the confectionery material being refined is evaluated by analyzing the quality of the already refined product. These consistency variations are compensated for by changing the milling distance or gap between the pre-refining machine cylinders.
  • a reduction or an increase of the area of the surface of the confectionery material particles is obtained, thereby differently distributing the fat present in said mass, and consequently either decreasing or increasing the consistency thereof.
  • Such an operating method based on a visual control of the end product exiting the refining machine, has the drawback that it operates only after having refined a part of the confectionery material, and, accordingly, with a considerable delay.
  • the aim of the present invention is to overcome the above mentioned drawbacks of the prior art and, in particular, provide a confectionery material pre-milling method and device allowing to hold the confectionery material consistency constant.
  • this is achieved by a method for pre-milling a confectionery material, in which the particle size of the particles of said confectionery material is reduced between two cylinders, characterized in that said method comprises the steps of measuring the load or spreading-apart force between said two cylinders, comparing the measured spreading-apart force with a reference spreading-apart force value, to define a force variation, defining, based on said spreading-apart force variation, a desired distance between said cylinders allowing to adjust a mutual position of said cylinders by feedback controlling said position based on the measured distance between said cylinders.
  • the confectionery material is milled between milling cylinders having a preset milling distance or gap and respective mechanically set revolution speeds.
  • milling cylinders having a preset milling distance or gap and respective mechanically set revolution speeds.
  • the mixing device supplies the pre-refining machine with a confectionery material the consistency whereof changes depending, for example, on the fat contents of the product and on natural variations of the mixer metering device or the characteristics of the used starting materials, then a variation of the load or spreading-apart force produced by the confectionery material passing through said cylinders will be provided.
  • the disclosed method As the load between the cylinders changes, a new size or value of the milling gap for holding the confectionery material consistency unaltered will be set, and, based on this new gap or cylinder distance, the mutual positions of the laminating cylinders will be adjusted.
  • the confectionery mass particles granulometry is changed, thereby changing the solid phase specific surface area, so as to properly distribute the fat contents, to recover the confectionery material mass consistency to the desired values.
  • the measured distance of said cylinders is changed in subsequent increments or decrements of a preset value to provide a spreading-apart force of said cylinders equal to the reference spreading-apart force value.
  • the distance between the laminating cylinders is measured, said measured distance is compared with the desired distance, and a variation of the distance constituting the reference for adjusting the mutual locating movement of said cylinder is defined.
  • the amount of the spreading-apart force measured by the cylinders together with the value of the cylinder measured distance is displayed.
  • the confectionery material pre-milling device for carrying out the method according to the present invention comprises a first swinging cylinder which can controllably swing with respect to a second cylinder supported at a fixed position and being characterized in that between the first and second cylinders a controllable adjusting device for feedback adjusting the position of the first cylinder with respect to the second cylinder is provided, that between the first cylinder and second cylinder a spreading-apart force transducer is provided, that said spreading-apart force transducer is operatively coupled to a driving and control device and that said driving and control device is operatively coupled to said feedback adjustment device for adjusting the mutual positions of said cylinders.
